DWO1DT995 Weed Trimmer Head Parts Replacement for Dewalt Weed Trimmer Head Cap Compatible with Dewalt String Trimmer Head with Weedeater Spring and Cap, Replacement Dewalt String Trimmer Cap DCST922

What It Is

This is a replacement trimmer head cap and spring set for Dewalt 20V MAX and 60V MAX string trimmers. It secures the spool inside the trimmer head and provides the tension needed for automatic line feeding.

Fitment & Compatibility

Before buying, confirm your trimmer model. This cap fits Dewalt models DCST922, DCST920, DCST925, DCST970, DCST972, and DCST923. It also works with the DWO1DT995 OEM part number. Measure the cap diameter: it should be roughly 1.5 inches. The spring is a standard coil type. If your trimmer uses a different head design (e.g., bump-feed vs. auto-feed), check that the cap shape matches the original. This is a direct replacement, not an adapter for other brands.

Key Things to Know

• Quality: Plastic cap is durable but not unbreakable—avoid overtightening. Spring is zinc-plated steel and resists rust.
• Installation: Tool-free swap. Remove old cap, replace spring, press new cap on until it clicks. Takes under 2 minutes.
• Common gotcha: If line doesn’t feed after replacement, the spring may be seated backward. The wide end of the spring faces the spool.
• Price point: At $8, it’s cheaper than buying a whole new trimmer head assembly. Good value for a wear item.

Should You Buy It

Buy this if your Dewalt trimmer’s cap is cracked, lost, or the spring is weak (line doesn’t advance). It’s perfect for DIYers who want a quick, cheap fix instead of replacing the entire head. Skip it if your trimmer model isn’t listed—wrong cap will not lock in place.
